I saw the QQ. He was pretty mad when he saw that he had folded to my JJ, but I did put 3/5 of my stack in pre-flop so he could have reasonably assumed I had KK or QQ. He also would have lost to Mr. Brainiac so it ended up being a wrong call that save him money.
Of course, I tilted after this hand and ended up washing out for the night. Stupid me.
I gotta develop discipline.
